itself.
9. If boiler and feeder are withdrawn from exploitation process, every three months

STATES OF IMPROPER BOILER’S FUNCTIONING
PROBLEM
CAUSE/SYMPTOM
REMEDY
Low heat
capacity of
device
gases channels obstructed
clean the channels through
washout wholes
lack of fresh air delivered to
boiler room
check blow-in ventilation,
improve its permeability
burning inadequate fuel
apply proper quality fuel (see
chapter 5.Fuel)
boiler power not up to heating
area
improper design and erection
of heating installation
improper
functioning
of
controller or fan
adjust controller’s settings up to
weather conditions or quality of
fuel, mainly feeder operation time
and fuel delivery pauses should be
changed (time for fuel burning off)
if controller does not work properly
Smoking
chimney draught not sufficient
check chimney’s permeability and
its parameters - see tab. height
and section to boiler’s power,
check if chimney end is not lower
than roof ridge
gases channels dirty
clean up boiler through washout
holes
sealing rope indoor and
washout openings worn
replace a rope (to be replaced
regularly)
orifices leading the air to retort
blocked
clean the retort, make orifices
permeable
improper assembly of boiler
and chimney connection
check accurateness
very low atmospheric pressure
improper position of smoke
throttle to current chimney
adjust sprocket position if it is
closed to much
